Turn and Lane-Change
Signals
An arrow on the instrument cluster
flashes in the direction of the turn or
lane change.
Move the lever all the way up or
down to signal a turn.
Raise or lower the lever until the
arrow starts to flash to signal a lane
change. Hold it there until the lane
change is complete. If the lever is
briefly pressed and released, theturn signal flashes three times.
If more flashes are desired,
continue to hold the lever.
The lever returns to its starting
position when it is released.
If after signaling a turn or lane
change the arrows flash rapidly or
do not come on, a turn signal
indicator light failure may have
occurred.
If a turn signal has failed, the lamp
may need to be replaced. See your
dealer.

9-34 Driving and Operating
Brakes
Antilock Brake
System (ABS)
This vehicle has ABS, an advanced
electronic braking system that helps
prevent a braking skid.
When the vehicle begins to drive
away, ABS checks itself.
A momentary motor or clicking noise
might be heard while this test is
going on, and it might even be
noticed that the brake pedal moves
a little. This is normal.
If there is a problem with ABS, this
warning light stays on. SeeAntilock
Brake System (ABS) Warning Light
on page 5-22. If driving safely on a wet road and it
becomes necessary to slam on the
brakes and continue braking to
avoid a sudden obstacle, a
computer senses the wheels are
slowing down. If one of the wheels
is about to stop rolling, the computer
will separately work the brakes at
each wheel.
ABS can change the brake pressure
to each wheel, as required, faster
than any driver could. This can help
you steer around the obstacle while
braking hard.
As the brakes are applied, the
computer keeps receiving updates
on wheel speed and controls
braking pressure accordingly.
Remember: ABS does not change
the time needed to get a foot up to
the brake pedal or always decrease
stopping distance. If you get too
close to the vehicle in front of you,
there will not be enough time to
apply the brakes if that vehicle
suddenly slows or stops. Always
leave enough room up ahead to
stop, even with ABS.
Using ABS
Do not pump the brakes. Just hold
the brake pedal down firmly and let
ABS work. You may hear the ABS
pump or motor operating and feel
the brake pedal pulsate. This is
normal.
Braking in Emergencies
ABS allows you to steer and brake
at the same time. In many
emergencies, steering can help
more than even the very best
braking.

.Tour: Modern theme which
features displays for audio and
navigation.
.Sport: Classic easy to read
Sports Car gauges.
.Track: Gauges design based on
Corvette Racing display with lap

Throttle Progression
Adjusts throttle sensitivity by
selecting how quick or slow the
throttle reacts to input.
Transmission Shift Mode −Paddle
Shift Automatic
.Adjusts to either a smoother or
firmer shift.
.Sport –Performance Algorithm
Liftfoot (PAL) recognizes
aggressive throttle maneuvers and holds lower gears for
greater engine braking and
enhanced vehicle control when
not using paddles. (Available in
Sport or Track mode.)
.Track
–Performance Algorithm
Shift (PAS) recognizes
aggressive cornering, heavy
braking, and high acceleration to
select and hold lower gears
when not using paddles.
Active Fuel Management (engine
cylinder shuts off)
4-Cylinder Mode
.Normal with automatic
transmission: The engine uses
8-cylinder mode when
accelerating, but changes to
4-cylinder mode when coasting.
.With manual transmission:
Active Fuel Management only
active in Eco mode.
.Off in Manual mode with
automatic transmission unless in
Eco mode.
.Eco keeps the engine in
4-cylinder mode unless heavy
acceleration is needed.
Exhaust (variable mode exhaust
system)
Changes when the variable exhaust
valves open.
Steering (Assist Effort)
Adjusts from a lighter steering feel
to reduced assist for more
steering feel.
Magnetic Ride Control (if
equipped)
Adjusts the shock dampening
firmness based on driving
conditions to improve comfort and
performance.
Launch Control
Available only in Track mode for
maximum “off–the–line” acceleration
when in Competitive or PTM modes.

more firmly, and re-apply the
accelerator to wide open
throttle.)
The Launch Control feature will
initially limit engine speed as the
driver rapidly applies the accelerator
pedal to wide open throttle. Allow
the engine rpm to stabilize.
A smooth, quick release of the
brake pedal, while maintaining the
fully pressed accelerator pedal, will
manage wheel slip.
After the vehicle is launched, the
system continues in Competitive
Driving Mode (except Z51 and Z06
with Magnetic Ride Control) or
Performance Traction Management
(Z51 and Z06 with Magnetic Ride
Control).
Competitive Driving Mode, PTM,
and Launch Control are systems
designed for a closed course race
track and not intended for use on
public roads. The systems are not
intended to compensate for lack of
driver experience or familiarity with
the race track.Limited-Slip Differential
(Except Z51 and Z06)
If equipped, the mechanical
limited-slip differential can give more
traction on snow, mud, ice, sand,
or gravel. It works like a standard
axle most of the time, but when
traction is low, this feature allows
the drive wheel with the most
traction to move the vehicle. For
vehicles with limited slip differential,
driven under severe conditions, the
rear axle fluid should be changed.
See Competitive Driving Mode on
page 9-43 andMaintenance
Schedule on page 11-2.
Limited-Slip Differential
(Z51 and Z06 Only)
If equipped, the Electronic Limited
Slip Differential (ELSD) is
automatically activated. ELSD
actively monitors vehicle sensors
and driver inputs to determine the
amount of change for the
conditions. With ELSD, the
vehicle has:
.Enhanced high-speed control.
.Improved traction through
corners, allowing more
acceleration.
.More precise steering.
.Increased vehicle agility.
.Integration with StabiliTrak.
For vehicles with limited slip
differential, driven under severe
conditions, the rear axle fluid should
be changed. See Competitive
Driving Mode on page 9-43 and
Maintenance Schedule on
page 11-2.
